Various tests on the inert-gas metal-arc welding of a corrosion resisting aluminum-magnesiummanganese alloy "ANP" have been performed with ANP-O and ANP-1/4 plates 1/4 in in thickness, and various consumable electrode wires, 2S, 52S. A54S, 56S and ANP. The present report Part 4 discusses the effect of porosities in weld metal on the mechanical properties of butt-welded joint, various microstructures of weld metal and heat-affected zone in the base metal, and the effects of filler wires and surface cleaning method on the corrosion resistance of welded joint. The main conclusions are as follows ; (1) The yield an-d tensile strengths were affected very little by weld porosities, provided porosities were less than the class No. 4 in JIS Z 2341. However, the bend ductility of butt weld was decreased with porosities greater than the class No. 2 or 3. The ANP weld had the best ductility. (2) The corrosion attack in sea water started at the weld toe, and progressed into the interior along the bond. ' (3) The effects of filler wires and surface precleaning methods weight loss on the corrosion./of butt weld and bead weld were scarcely detected, because the effects of local difference and temper of base plates were more pronounced. The effect of corrosion on the mechanical properties and fatigue strength should be tested furter. (4) From the points of view of mecanical properties, cracking resistance, bend ductility and corrosion resistance, the best filler for ANP plate seems to be the ANP wire, and next A54S, and the third 56S, while 43S wire should be avoided.
